【摘要】 采用化学还原法,以金属硝酸盐和氯化钯为前驱体,制备了含钯担载双金属催化剂Cu -Pd/C、Mo -Pd/C、Ni-Pd/C、Co -Pd/C、Mn -Pd/C ,并用XRD法和XPS法进行了表征。用碘苯与丙烯酸的Heck反应对这些催化剂的活性进行了评价。这些催化剂在碘苯与丙烯酸的Heck偶合反应中显示出比Pd/C催化活性高,其中,Mo显示出最高的协同效应。更多还原

【Abstract】 The supported bimetallic catalysts, Mo-Pd/C, Mn-Pd/C, Cu-Pd/C, Co-Pd/C and Ni-Pd/C, which were first prepared by reduction with KBH4, showed high activity in the Heck reaction of phenyl iodide with acrylic acid The addition of these nonpalladium metals promoted the catalytic activity of Pd for Heck reaction obviously and molybdenum shows the highest synergistic effect更多还原
